342013 divided by 12 
Our goal is to divide 342013 by 12.

Advancing to step 1:
3 divided by 12 is 0 with a remainder of 3.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 3 to get 3.
Bring next digit (4) of the dividend behind the 3 and repeat the process: 34 / 12

Step 2:
The number 12 fits into 34 2 times, leaving a remainder of 10.
Write down 2 as next digit of the result. 
Result so far: 2.0
Subtracting 24 from 34 leaves us with 10.
Take the next digit (2) from the dividend and append it to 10, then repeat: 102 / 12

Going ahead to step 3:
12 goes into 102 8 times with a remainder of 6.
The next digit of our result is 8. 
Result so far: 28.0
Deduct 96 from 102 and we're left with 6.
Take the next digit (0) from the dividend and append it to 6, then repeat: 60 / 12

On to step 4:
The number 12 fits into 60 5 times, leaving a remainder of 0.
The number 5 becomes the next digit in our result. 
Result so far: 285.0
If we take 60 away from 60, we end up with 0.
Include the next digit (1) from the dividend after 0, then repeat: 1 / 12

Let's proceed to step 5:
12 goes into 1 0 times with a remainder of 1.
The next digit of our result is 0. 
Result so far: 2850.0
The remainder is 1 after subtracting 0 from 1.
Append the next digit (3) from the dividend to 1 and continue with: 13 / 12

Let's proceed to step 6:
12 can be fit into 13 1 times, resulting in a remainder of 1.
The number 1 becomes the next digit in our result. 
Result so far: 28501.0
The remainder is 1 after subtracting 12 from 13.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

On to step 7:
12 goes into 10 0 times with a remainder of 10.
The number 0 becomes the next digit in our result. 
Result so far: 28501.0
The remainder is 10 after subtracting 0 from 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Advancing to step 8:
12 can be fit into 100 8 times, resulting in a remainder of 4.
Put 8 as the next digit of the answer. 
Result so far: 28501.08
Subtract 96 from 100 to get 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Going ahead to step 9:
The number 12 fits into 40 3 times, leaving a remainder of 4.
The number 3 becomes the next digit in our result. 
Result so far: 28501.083
If we take 36 away from 40, we end up with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Moving on to step 10:
The number 12 fits into 40 3 times, leaving a remainder of 4.
Use 3 as the next digit of our solution. 
Result so far: 28501.0833
The remainder is 4 after subtracting 36 from 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

The quotient of the division is 28501.0833, and the remainder is 4e-05.
